Latin-ISO (XXIII) CCCXXVIII spirandi ratio Filtra ad Papaver et respiratoriorum usum

ISO 23328-1: MMVIII Heading Ratio Filtra ad Papaver et Respiratoriorum Use- Part I: Salis-Test modum ad assess filtration perficientur

Haec parte ISO (XXIII) CCCXXVIII dat modum test ad perpendendis filtration perficientur de spirandi ratio Filtra (BSF).

In test, in BSF provocatur cum sodium chloride particulas maxime penetrantes magnitudine rhoncus, 0.1 ~ 0.3μm.

Apparatus

Flowmeter, cum accurate de ± V% de ipsa valorem ut metiri:
